Thailand's Land Bridge and the Moving Map It Must Account For
Our first piece examined the domestic anatomy of the Land Bridge, covering the feasibility numbers, the enabling legislation, the public mandate, and the recent pivot toward an oil and gas pipeline corridor. This follow-up lifts the lens to the external environment the project must succeed in. The 90-day review now led by Finance Minister Ekniti Nitithanprapas is the right instinct. A major national project should be tested against the world as it is, rather than the world of the original study.
Our aim is to supply that test, drawing on the chokepoint data, the energy forecasts, the shipping trends, the regional competition, and the geopolitics, so that whatever decision follows rests on the fullest possible picture. The questions we raise are offered to widen the aperture, not to close it.
Key takeaways
The strategic logic behind the Land Bridge is sound, but the project is being justified against assumptions about trade, energy, and geopolitics that have shifted since the original 2024 study.
The Strait of Malacca is the hardest major chokepoint to close, and the real disruptions of 2024 to 2026 happened at Hormuz and in the Red Sea, where a Thai corridor offers no remedy.
The container case is weak because cargo must be double-handled across the peninsula, and the corridor would have to outcompete Singapore's Tuas Port and Malaysia's Port Klang, which is why no major shipping line has committed.
The pivot to an oil and gas pipeline ties a 50-year asset to energy-demand forecasts that the forecasters themselves no longer agree on.
China already operates overland bypasses through Myanmar and Laos, and the Arctic route is slowly opening, so external demand for a Thai corridor is more limited than the headlines suggest.
A smaller, staged design built around an upgraded Ranong port and BIMSTEC trade could capture most of the value at far lower fiscal, environmental, and geopolitical risk.
The case, stated fairly
The Land Bridge addresses a real problem. The Strait of Malacca carries more than 90,000 vessels a year and roughly a quarter of the world's traded goods, and traffic is projected to grow about 2% annually toward 2030, with congestion and accident rates climbing alongside it.
For China, which routes around 80% of its oil imports through the strait, this is the "Malacca dilemma" first named under Hu Jintao, a genuine strategic vulnerability. The case is not academic.
Iran's near-closure of the Strait of Hormuz since early 2026 has made chokepoint exposure tangible across Asia, and Indonesia's recent suggestion that it might charge passage fees in the Malacca Strait has sharpened the point further. Prime Minister Anutin Charnvirakul has framed the project around exactly this shift, arguing the country needs a more self-sufficient posture toward maritime risk.
The official proposal responds at scale. Now costed at around 997 billion baht (about USD 28–29 billion), revised from the 1.001 trillion baht in OTP's May 2024 study, it pairs deepwater ports at Ranong on the Andaman coast and Chumphon on the Gulf, connected by some 90 km of motorway and dual-track rail, structured as a 50-year PPP Net Cost concession under a single private operator.
Design capacity is about 19.4 million TEUs at Ranong and 13.8 million at Chumphon. Its proponents project that the corridor could cut transit time by up to four days and shipping costs by around 15%, lift GDP by about 1.5%, and create up to 280,000 jobs by 2039, while anchoring a Southern Economic Corridor of industrial and logistics zones, the "value creation on Thai land" that is the strongest version of the rationale.
There is also a real regional-connectivity prize that deserves more attention than it gets. Ranong is today badly underused, having handled just 1,323 TEUs in 2023 and serving little more than an offshore oil rig, yet it sits at the natural gateway to the Bay of Bengal. Building on a 2021 memorandum with Chattogram in Bangladesh and the 2022 BIMSTEC connectivity master plan, an upgraded Andaman gateway could open direct routes toward Chennai, Colombo, and onward to Nepal, Bhutan, and northeast India.
Public sentiment is mixed rather than settled. A recent Nida Poll found 67% support among southerners aware of the project, but close to a third opposed it, and more than half said they understood it only a little. Opposition is most intense among the communities along the route itself, which is a signal worth taking seriously rather than reading the headline support figure as a settled mandate.
The instinct, in short, is defensible. The question this piece engages is narrower. Against an external environment that has moved considerably since 2024, which version of this instinct holds up, and what should the review weigh before committing capital for half a century?
What the chokepoint map says
The most authoritative reference is the US Energy Information Administration's chokepoint series, and it is unsentimental.
By the EIA's count, the Strait of Malacca is the world's largest oil transit chokepoint, moving about 23.2 million barrels a day in the first half of 2025, close to 29% of all seaborne oil, alongside substantial LNG volumes, with China accounting for roughly 48% of the crude. Hormuz follows at around 20 million barrels a day, about a fifth of world consumption. These are large, real exposures.
The distinction that matters for project design is the geography of redundancy. Hormuz is a true single-point chokepoint, with one entrance, one exit, and, as the EIA notes, very limited alternatives if it closes. Malacca is more resilient.
Vessels can divert through Indonesia's Sunda and Lombok straits, a detour that adds time and fuel cost but cannot be easily sealed. A scenario in which a major power blockades both ends of Malacca at once would be a system-wide conflict, the kind in which fixed infrastructure on the Thai peninsula would itself be exposed. This does not defeat the project's logic; it refines it.
The strongest security case is congestion relief and route diversification under ordinary and moderately stressed conditions, not insurance against a total Malacca closure, which is both the least likely chokepoint failure and the one a fixed corridor could least reliably backstop.
Safety is part of the proponents' case, and piracy belongs in that ledger honestly. Incidents in the Straits of Malacca and Singapore rose to a 19-year high in 2025, with 108 reported, up 74% on the year, which at first glance strengthens the argument for an alternative route. The detail complicates it.
Almost all of those cases were low-level opportunistic theft committed at night, with no severe incidents and most causing no injury; 107 of the 108 occurred in the Singapore Strait rather than the Malacca Strait itself; and the numbers fell sharply once Indonesian police made arrests mid-year, the signature of a problem that responds to enforcement rather than one that requires rerouting global trade.
A land bridge would not remove the exposure in any case, since vessels still transit the piracy-prone approaches, and concentrating high-value cargo at two fixed ports and along an overland corridor through a region with its own security sensitivities introduces a different set of risks rather than eliminating them. Piracy is a genuine cost of the status quo. It is not, on the evidence, a cost a transhipment corridor resolves.
The natural experiment has already run
A useful feature of this moment is that we are not theorising about how shipping responds when a chokepoint fails. Between late 2023 and 2026, the world ran the experiment twice.
When Houthi attacks closed the Bab el-Mandeb to most commercial traffic, transits through it and the Suez Canal collapsed. Container volumes through Suez fell roughly 75% in 2024, Egypt lost well over USD 8 billion in canal revenue, and LNG flows through the canal dropped from 32.4 million tonnes in 2023 to 4.2 million in 2024. The market's response was to reroute around the Cape of Good Hope, which added time but required no new fixed infrastructure and no double-handling.
Two findings bear on a transhipment corridor.
First, routing decisions proved sticky. Even after the last Houthi attack in late September 2025, Suez traffic stayed around 60% below its 2023 level into early 2026. Networks rebuilt around an alternative route do not snap back when the risk premium falls.
Second, when Hormuz closed in spring 2026 and the Houthis resumed Red Sea attacks, both Middle Eastern corridors were blocked at once, yet the disruption sat at the source and in the Red Sea, not at Malacca. A barrel that cannot leave the Gulf is not helped by a corridor across the Thai isthmus.
The constructive reading is that the review's scenario set should distinguish carefully between source, Red Sea, and Malacca-specific disruptions; they are different problems with different remedies, and only the last is one the Land Bridge directly addresses.
The harder economics of handling, competition, and committed cargo
Beyond geopolitics sits a more mundane but decisive question, namely whether shippers would actually use the corridor.
Independent analysis from the ISEAS – Yusof Ishak Institute sets out the core friction clearly. A land bridge requires every container to be lifted off one vessel, moved across the peninsula, and reloaded onto another, a process that can take a day or more and depends on a same-sized vessel waiting on the far coast to align with each arrival. Once double-handling, transit, and reloading are counted, much of the headline time saving can be eroded, while cargo-loss risk and insurance costs rise. This is the same conclusion the domestic feasibility work reached, and it is why the container case has always been the project's weakest leg.
The competition compounds the problem. The Land Bridge would not merely divert traffic from a congested strait; it would have to win cargo from some of the most advanced ports on earth.
Singapore's Tuas Port is being built toward a 65-million-TEU capacity as the world's largest automated terminal, and Malaysia is expanding Port Klang from 14 to 27 million TEUs while extending its East Coast Rail Line.
Against these, the Thai ports' planned capacity is modest, and Singapore's surrounding ecosystem of financing, insurance, bunkering, and ship repair is not easily replicated. The market signal is consistent with this. More than 100 Thai and foreign companies attended OTP's investor event in May 2024, but no major global shipping line has committed, and Thailand has had to propose a 300-billion-baht (about USD 9 billion) state infrastructure fund to underwrite confidence. Demonstrating committed anchor cargo, rather than expressions of interest, is the single most useful thing the review could require before construction.
The commodity the pipeline would carry
The most consequential change in scope is the proposed oil and gas pipeline corridor. It is worth noting that OTP's completed studies do not yet include the pipeline. Land has been reserved, but the economics have not been formally assessed, which makes the review the natural place to test it against a demand forecast running to the 2079 end of the concession.
Here the forecasts diverge, and the divergence widened in 2025. On oil, the IEA's Oil 2025 projected demand rising to a plateau near 105.5 million barrels a day around 2030 before easing, with Chinese demand peaking as early as 2027. Its November World Energy Outlook 2025 then widened the range. Its Current Policies Scenario sees oil demand still rising in 2050, while its Stated Policies Scenario keeps a peak near 2030.
OPEC, by contrast, forecasts no peak at all through the 2040s. The band of credible outcomes is wide enough to swing the pipeline's business case from strong to marginal.
Gas carries a more durable demand story. Shell's LNG Outlook 2025 sees global LNG demand rising about 60% by 2040, with Asia supplying roughly 70% of growth, though that story is contested. Analysts note that emerging-Asian demand has consistently undershot earlier forecasts (the combined imports of Thailand, Vietnam, the Philippines, Bangladesh and Pakistan reached 27 MTPA in 2024 against the 56 MTPA once projected for 2025), and that the IEA has trimmed its 2040 gas outlook as renewables advance.
There is also a geographic point. A Kra-Isthmus pipeline shortens the Andaman-to-Gulf leg, but cargo destined for China still has to cross the South China Sea, so the corridor is a partial bypass for the anchor buyer rather than a complete one. None of this rules the pipeline out; it argues for sizing oil and gas separately, each against a range of forecasts.
China's overland alternatives
Any demand estimate must account for the routes the principal beneficiary has already built. China's answer to the Malacca dilemma runs primarily overland through its southwest.
The Sino-Myanmar gas pipeline has operated since 2013 and the crude pipeline since 2017, carrying oil from the deepwater terminal at Kyaukphyu directly to Kunming and bypassing both Malacca and the South China Sea. To the east, the China–Laos–Thailand connectivity corridor and the China–Laos railway already link Kunming toward the region, with Thailand's own Bangkok–Nong Khai high-speed line intended to complete the chain.
Two features of this picture matter for Bangkok.
First, China's existing bypass is real but increasingly fragile. The Kyaukphyu port has been delayed for over a decade, and Rakhine State is now a conflict zone where the Arakan Army controls 14 of 17 townships and has encircled the terminal. That instability is one reason China might value a Thai option as additional insurance, but also why it is likely to treat a Thai corridor as a secondary hedge rather than a primary route.
Second, China's appetite for funding expensive overseas megaprojects has narrowed. Its BRI footprint in Thailand is thinner than in Malaysia or Indonesia, and it has shown limited interest in fully financing comparable schemes such as Cambodia's Funan Techo Canal. This is consistent with the historical pattern our first piece documented, namely two decades of expressed foreign interest, including from DP World, without committed capital.
The Kyaukphyu experience also carries a sober lesson, which is that strategic infrastructure does not become safer once it acquires strategic value.
The strongest version of the pro-Land-Bridge case engages this directly. Its advocates argue that with rail running north from the Thai ports into Laos and southern China, cargo from China's interior could reach the Indian Ocean by travelling south through Thailand to the Andaman coast, instead of looping out through the South China Sea and back around through Malacca.
The ambition is real, and China is plainly building outward. Its US$10 billion Pinglu Canal, due to open at the end of 2026, gives the landlocked southwestern provinces their first direct inland waterway to the sea. But that canal opens onto the Gulf of Tonkin on the South China Sea side, which serves ASEAN trade rather than bypassing Malacca for cargo heading west. And for the one flow a Thai corridor would genuinely shorten, southwestern China reaching the Indian Ocean, China has already built its own answer in the Kunming-to-Kyaukphyu route through Myanmar.
A Thai rail-and-Andaman corridor would therefore compete with a path Beijing has spent fifteen years building, which is why the routing argument, real as it is, does not on its own turn the corridor into a primary artery.
A crowded neighbourhood
The contest is not only between Beijing and Washington.
India watches the Bay of Bengal closely, and reads Chinese involvement in regional ports, Chattogram among them, through the lens of strategic encirclement, responding with the India–Myanmar–Thailand Trilateral Highway and expanded naval facilities in the Andaman and Nicobar Islands. Yet New Delhi is not uniformly opposed; it has also signalled interest in participating, which points to the real opportunity. A corridor financed and used by a single bloc invites the suspicion of all the others. A corridor positioned as a neutral, multi-stakeholder ASEAN and BIMSTEC asset, open to Gulf, Japanese, Indian, and Western participation alongside Chinese, is both more financeable and more defensible.
The diversification of partners is not only a commercial hedge; it is the project's best protection against being drawn into someone else's rivalry.
The Arctic as a slow structural variable
Over a 50-year horizon, the review should also weigh a trend moving against the corridor's transhipment premise.
The retreat of Arctic sea ice is opening the Northern Sea Route along Russia's coast, which for the China–Europe leg offers a path up to 40% shorter than the Malacca–Suez corridor and bypasses Malacca entirely. Volumes remain marginal.
The 2025 season recorded 103 transit voyages carrying about 3.2 million tonnes, under 0.1% of global container flows, and the route is seasonal and dependent on Russian icebreakers. But the direction is consistent. Chinese container voyages rose from 7 in 2023 to 11 in 2024 to 14 in 2025.
This is not a near-term competitor, but for a concession running to 2079 it bends away from the equatorial transhipment model, and the volume assumptions should be stress-tested against it.
Climate, and the lesson from Panama
Climate cuts in another direction worth studying, because the cleanest real-world comparator for transit infrastructure under stress is the Panama Canal.
Drought cut the canal's daily transits from the normal 36–38 to as few as 22–24 in late 2023 and produced a 29% drop in transits in fiscal 2024, with LNG transits down two-thirds; peer-reviewed modelling suggests such droughts could become commonplace by century's end under higher-emissions pathways. The instructive part is the response.
Rather than build a general-purpose alternative, the Panama Canal Authority is constructing a narrow, purpose-built pipeline for natural gas liquids, a targeted fix for one cargo type and one failure mode. That is the disciplined expression of the land-bridge idea, and it points toward a design principle the review might adopt, which is to scope the corridor to the genuine, evidenced need rather than to the full basket of contingencies at once.
Security, neutrality, and Thai statecraft
Several strategic considerations belong in the review, not because they are disqualifying but because they carry real, recurring costs the headline figure omits.
The most immediate is defence.
A large strategic installation on the southern peninsula would acquire strategic value, which in a regional conflict is also strategic exposure, in the way energy infrastructure elsewhere has become a target. The lifetime cost and feasibility of protecting such an asset belong in the fiscal model from the outset, not as an afterthought.
A chokepoint is not only a target. It is an instrument, something other powers will want to control, influence, or deny in a crisis, which draws the host into conflicts it did not choose and makes its own territory the bargaining table.
The recent record is plain. Iran has repeatedly used the threat of closing the Strait of Hormuz as coercive leverage and acted on it in 2026. Egypt's Suez Canal has been both a source of rents and, since the 1956 crisis, a recurring object of great-power contest.
Panama shows the modern form most clearly. Since January 2025 the United States has pressed to "take back" the canal over alleged Chinese influence, the dispute reached the UN Security Council, and Panama, with limited means of its own, has found itself caught between two superpowers, its sovereignty over its signature asset suddenly in question.
The lesson for Thailand is that the rents and relevance a strategic corridor confers in peacetime come with a standing liability in conflict, and that the host's stakes, its territory, its neutrality, and its freedom to stay out of other people's wars, are the highest of anyone's. A stretch of the isthmus that today no one has reason to fight over would become something others have an interest in controlling.
A further consideration is alignment, and here Thailand's record is a genuine asset. The kingdom has long managed great-power pressure with skill, and recent practice shows the instinct intact. It self-financed its USD 5.3 billion share of the China–Thailand railway rather than accept Chinese loan terms it judged unfavourable, taking the technology while keeping the debt off Beijing's books.
The same balancing instinct, traceable to its careful navigation of a canal concession in 1897, is precisely what would let it accept investment in a corridor while preserving room to manoeuvre.
The risk to guard against is the dependency trap, a financing structure that quietly converts an infrastructure deal into a foreign-policy commitment. The point for the review is simply that the corridor's ownership and funding model is a strategic decision as much as a commercial one, and is best designed with both lenses at once.
Delivery, and learning from Thailand's own record
Finance Minister Ekniti has rightly emphasised that a project of this scale must be conducted with transparency, and Thailand's own infrastructure history is the most useful guide to why.
The country has built world-class infrastructure, but it has also seen ambitious mega-projects falter when execution outran their justification. The Hopewell elevated rail and road scheme, signed in 1990, was terminated in 1998 at roughly 13% completion, leaving a long-running compensation dispute; the Klong Dan wastewater project reached around 90% completion before being abandoned amid governance failures and never entered service. These are not arguments against building; they are the reasons phased delivery, independent oversight, and demand-tested staging matter. Execution risk is not only fiscal.
The corridor's footprint is large, with sea reclamation alone running to nearly 7,000 rai, and its port, rail, and motorway works would touch mangrove, wetland, and fishing grounds near the Ranong Biosphere Reserve, where the full environmental and health assessment is not yet complete and local communities have organised against the current design. The review's remit already covers environmental, social, and community impacts, and because these costs and the time they take to resolve scale with the footprint, they are a further reason a smaller, staged design carries less risk of delay, dispute, and stranded investment.
A corridor structured so that early phases must prove their economics before later phases proceed, rather than a single 50-year concession committed up front, would align the project with the lessons Thailand has already paid to learn, and with the transparency standard the review itself has set.
What the review can usefully model
The fair conclusion is not that the Land Bridge should not proceed, but that the version most likely to succeed is the one tested honestly against a world in motion. A review worthy of the decision would treat the following as live variables rather than fixed assumptions.
That chokepoint risk is not monolithic, since source, Red Sea, and Malacca-specific disruptions are distinct, and the corridor's insurance value applies mainly to the last and least likely of them.
That the container case depends on out-competing Singapore and Malaysia and on real double-handling costs, which is why committed anchor cargo, not expressions of interest, should be the test before construction.
That the pipeline's viability rests on oil and gas demand forecasts now spanning a wide band, best assessed separately.
That China's existing overland routes, India's ambivalence, and the maturing Arctic option all shape how much external demand a Thai corridor can realistically anchor.
That climate argues for narrow, demand-tested scope over an omnibus design, as Panama's own response illustrates.
That the environmental, community, and permitting burden scales with the project's footprint, and is lighter for a smaller, staged design.
That hosting strategic infrastructure carries lifetime costs the headline omits, including the defence of a new target, the wartime-leverage liability that comes with owning a chokepoint, and the diplomatic exposure of the financing model.
There is a convergence here that should encourage the debate rather than divide it. Some of the project's own supporters now argue that its real value lies not in the ports but in the rail system and the inland dry ports that would spread economic activity into the north and northeast, and that the goal should be to make Thailand a connection point in regional supply chains rather than a passage the world's trade merely flows through. That case has been made publicly by proponents including Pheu Thai MP Thongtham Wechayachai.
It is a serious argument, and it points in the same direction as the analysis above. When the project's advocates themselves locate its worth in the railways and the inland value rather than the transhipment ports, that is the clearest signal that the defensible version is the smaller, rail-and-interior one rather than the trillion-baht port-led design.
The constructive path our first piece pointed toward remains the most promising, and independent analysis now converges on it.
Rather than a trillion-baht new-build competing head-on with established hubs, Thailand could capture most of the genuine benefit by upgrading the underused Ranong port as a Bay of Bengal gateway and deepening Laem Chabang's integration with the Eastern Economic Corridor and the China–Laos railway, a smaller, staged, BIMSTEC-oriented strategy that delivers real value at a fraction of the fiscal and environmental risk. That version is less dramatic than the trillion-baht headline. It is also far more likely to become an asset the country is glad it built.
The ambition behind the Land Bridge is legitimate, and the strategic concerns driving its revival are real. The 90-day review is the right moment to align that ambition with the world the project will actually operate in.
We offer this analysis in that spirit, fair, evidence-based, and directed at the variables rather than at any institution or individual, in the hope that it helps the public and decision-makers alike think more broadly and more deeply about a choice that will outlast us all.
